Malachi 2:1-2

Young's Literal Translation

2 And now, to you [is] this charge, O priests,

² If ye hearken not, and if ye lay [it] not to heart, To give honour to My name, said Jehovah of Hosts, I have sent against you the curse, And I have cursed your blessings, Yea, I have also cursed it, Because ye are not laying [it] to heart.
